Taw qhia ntawm CAS: 2050-94-4|N-CAPRYLIC ANHYDRIDE
Dipentyl carbonate (DPC) yog carbonate ester tau los ntawm cov tshuaj tiv thaiv ntawm pentanol nrog carbon dioxide los yog carbonate pub. Nws yog ib qho kev txaus siab nyob rau hauv thaj tsam ntawm ntsuab chemistry vim nws muaj peev xwm siv los ua cov kuab tshuaj tsis muaj tshuaj lom thiab ua ib qho nruab nrab hauv kev sib txuas ntawm ntau cov organic tebchaw. Lub synthesis ntawm DPC tau tshawb pom los ntawm cov kev hloov pauv hloov pauv siv cov kua ionic yooj yim ua cov catalysts, uas muaj lwm txoj hauv kev zoo rau ib puag ncig.

Kev Tshawb Fawb Daim Ntawv Thov CAS: 2050-94-4|N-CAPRYLIC ANHYDRIDE
Transesterification hauv Polycarbonate Manufacturing
Lee et al. (2003) tau hais txog lub luag haujlwm ntawm diphenyl carbonate, ze ze rau dipentyl carbonate, hauv kev tsim cov khoom tsis-phosgene polycarbonate. Cov txheej txheem no suav nrog cov transesterification ntawm dimethyl carbonate nrog phenol, siv dibutyltin oxide ua catalyst. Qhov sib ntxiv ntawm alkyl lossis aryl sulfonic acid txhim kho cov haujlwm catalytic ntawm dibutyltin oxide hauv cov txheej txheem no (Lee et al., 2003).
Membrane Tsim los ntawm Thermally Induced Phase Separation
Lin et al. (2008) tau tshawb xyuas kev siv cov diphenyl carbonate raws li ib tug diluent nyob rau hauv kev npaj ntawm microporous polyvinylidene fluoride (PVDF) daim nyias nyias los ntawm ib tug thermally induced theem-sib cais txoj kev. Txoj kev tshawb no pom tias tsis tshua muaj polymer concentration thiab siab quenching kub ua rau daim nyias nyias nrog qhov pore loj, qhia txog lub peev xwm ntawm diphenyl carbonate hauv kev tsim cov qauv membrane (Lin et al., 2008).
Nanocomposite Catalysts hauv Diphenyl Carbonate Synthesis
Kev tshawb fawb los ntawm Wang et al. (2021) tau tsim ib txoj hauv kev los npaj PbZr nanocomposite catalysts, ua kom pom lawv cov kev ua tau zoo hauv kev sib xyaw diphenyl carbonate. Qhov kev tshawb fawb no muab kev nkag siab zoo rau cov qauv-kev sib raug zoo ntawm nanocomposites thiab lawv cov peev txheej siv hauv kev sib xyaw ntawm ntau yam carbonates, suav nrog dipentyl carbonate (Wang li al., 2021).
Green Solvents nyob rau hauv Palladium-Catalyzed Hloov Reactions
Schäffner et al. (2008) tshawb nrhiav kev siv cov organic carbonates, xws li propylene thiab butylene carbonate, nyob rau hauv palladium-catalyzed asymmetric allylic hloov cov tshuaj tiv thaiv. Lawv txoj kev tshawb fawb tau lees paub qhov muaj peev xwm ntawm cov kuab tshuaj ntsuab no, uas tsis tshua muaj kev phom sij rau ib puag ncig, rau kev hloov pauv catalytic. Qhov no qhia txog kev siv tau ntawm ntau yam carbonate tebchaw, suav nrog dipentyl carbonate, hauv cov txheej txheem tshuaj lom neeg ntau dua (Schäffner li al., 2008).
